Abstract

The invention refers to the mixing of gas or gases, with air, in a controllable ratio, by means of a mixing apparatus wherein the entrance air is forced in a complete developed rotation stream, by which a strong suction pressure is created in the centre, so that gas can be sucked in ratio independent of the total volume per second.
The mixing ratio of gas and air is controlled through an adjustable angle of the air entrance nozzles (3). The rotating airstream is accelerated in the radial entrance plane and via a logarithmic curved profile, the airstream is guided in the axial outlet direction of the mixing apparatus. The rotating airstream develops a centre-core stream, where inside it a maximal under-pressure is created. By this underpressure, the main gasstream can be sucked and mixed with the airstream via the whirl grates (24), which are fixed in the outletsection just in front of the mixture outlet valve (25,26).
